RADIATOR.

SPECIFICATION forming part of Letters Patent N 0. 451,944, dated May 12,1891.

Application filed August 1, 1890.

To all whom it may concern.-

Be it known that I, FRANCIS MARAK, J r., of Everest, in the county ofBrown and State of Kansas, have invented certain Improvements inRadiators, of which the following is a specification.

My invention has reference to a reducingdrum in which the products ofcombustion are directed rapidly upward and downward through a series offines, the course being varied and determined by valves.

The aims of the invention are to simplify the construction and to securethe passage of the currents directly and repeatedly through the drum byone or more of its flues, in order to cause the burning or carrying awayof the solid matters which may lodge therein, and thus keep theapparatus clear and in good operative condition.

In the accompanying drawings, Figure l is a perspective view of myradiator with portion broken away to show the internal construction.Fig. 2 is a horizontal section of the same midway of its height. Fig. 3is a view showing the internal partitions removed. Fig. 4: is ahorizontal section on the line a; m, Fig. 1, looking downward. Figs. 5and 6 are vertical sections on the lines m 00' y y, Fig. 2,respectively.

Referring to the drawings, A represents an upright cylindrical body ordrum of sheet metal provided at the bottom with an inletneck a, throughwhich the products of combustion are admitted into a base-chamber b,lying below the horizontal division 0. At the upper end the body isprovided with a discharge-neck d and contains a top chamber e, lyingabove the horizontal division-plate f. The plates 0 and f are ofcast-iron of the full diameter of the drum and fixed in place by boltsor otherwise. The space between these plates is divided by verticalpartitions radiating from the center, and hereinafter described indetail, into equal flues or passages 1, 2, 3, 4:, and 5. The flue lcommunicates at its lower end directly and constantly with thebase-chamber through an opening it. The top of flue 1 is permanentlyclosed by the overlying division-plate; but a lateral opening 1' leadsfrom its upper end into the top of flue 2, which is provided at its topwith the upwardly-opening hinged valve 70, operated Serial No. 360,631.(N 0 model.)

eral opening pinto flue 5. A hinged valve q, controlled by theprotruding handle q, may be turned, so as to close the top of eitherflue at or flue 5 or leave both open. A hinged valve .9, with a handle5, is located at the lower end of flue 5, and may be turned down to shutoff communication with the base-cham:

ber or raised to permit the products to pass directly upward into theflue 5 and also through an openingp into flue '4. A hinged valve t,having a handle it, serves to open and close communication between thebase-chamber and the lower end of flue 3.

The operation is as follows: The valve q being adjusted to close the topof flue 4 and the other valves being closed, the products of combustionascend from the base-chamber directly into flue l, and ascending thereinescape laterally through the opening into the top of flue 2, in whichthey descend until they pass through the bottom opening into the flue 3.Ascending in this flue, they pass in turn through the lower opening intothe top of flue 4:, through which they descend and pass at the bottominto flue 5, through which they ascend into the top chamber, and thencethrough the delivery-neck at the top. By properly adjusting the valvesthe course of the products through the apparatus maybe materiallylessened. When it is desired to give a direct or unobstructed draft,either for the purpose of starting the fire or for the purpose ofblowing out and carrying away the soot or other solid matters which mayhave accumulated, it is only necessary to open all the valves, whereuponthe products will ascend directly through flue 1, and pass thencethrough opening and valve 70. The products entering valve 5 will ascendin part directly through the valve 5 and in part through the opening pand flue 4 into the top chamber. The products entering past valve i willascend in part through the valve 2, directly into the top chamber, andin part through flue 3, and thence through the lateral. opening at itstop through flue 4. It will be observed that a practically straight ordirect passage is thus afforded through each and all of the fines.

In order to reduce the labor of assembling the parts and admit of thepartitions being held securely in position, I recommend the constructionshown in Figs. 2 and 8,in which the five partitions are formed by threeplates. A sheet of metal ac, cutaway at its corners, as shown, to affordpassages between the fines, is bent longitudinally, so as to present a Vform in horizontal section and provided with holes 00' at. A secondplate w, having an indentation in one corner, is bent in like manner andprovided with holes w "w. A third and flat plate y is provided withoblique slots 1 Now the angular plates to and 0a are inserted endwiseinto the drum, with their angular portions at the center and their outeredges seated against the walls of the drum. The third plate y isinserted into the drum between them, one edge being seatedagainst thewall of the drum, while the other and slotted edge is seated between theangular plates. Bolts 2" are inserted through the holes in the angularplates and through the slots of the intervening plates. Before the boltsare tightened the plate y,which was left in an elevated position, isforced downward, when byreason of its inclined slots it is carriedoutward tightly against the wall of the drum, and also acts on the otherend to force the angular plates in the opposite direction against thedrum. In this way the several parts are forced and held tightly to theirplaces. The outer edges of the plates are seated between angular strips2 riveted to the inside of the drum.

Having thus described my invention, What I claim isl. The cylindricalbody having the top and bottom chambers therein, the division-plates,and the intermediate vertical lines com municating successively at theupper and lower ends, in combination with the two valves at the lowerend and the two valves at the upper end.

2. The cylindrical body or shell, in combination with theangulardivision-plates-w and x, the intermediate obliquely-slotted plate, andthe connecting-bolts.

3. In a radiator, an upright body'divi'ded into a series of verticalflues, said fines communicatin g successively at the'topand bottom tocompel a serpentine course of the products of-combustion, in'combination with top and bottom valves to open the ends of the fines andpermit a direct vertical passage of the products through all the -flues.

In testimony whereof I hereunto set my hand, this th day of October,1889, in the presence of two attesting witnesses.
